The TLC5920 is an LED driver incorporating a

16-channel shift register, data latch, and constant

current circuitry with current value control and

8-channel common driver into a single chip. The

constant output current is capable of 30 mA for 16

bits simultaneously, and the current value can be

set by one external register. This device also

includes a 16-bit segment driver and 8-bit

common driver; therefore, the monocolor LED

array with 16 × 8 dots can be driven by only one

TLC5920, and a two-color LED array with 16 x 16

dots can be driven by two TLC5920s.
